Changeling

Goose goes undercover, using his biodefences to change his form to an insect-
like humanoid, on the Deltoid rock, which has been taken over by the inmates
and is going to explode dangerously close to a planet. The General
and MaCross are fighting each other who should
rule the station, and Goose is able to make use of it, at least
long as they don't find out who he really is...
